DEVICE FOR SECURING TIRES TO WHEEL-RIMS.

Specification of Letters Patent.

Patented Jan. 2-11, 1 9111.

Application filed January 28, 1910. Serial No. 540,711.

To all whom it may concern:

Be it known that I, AUGUs'rn Louis Cami, a citizen of the FrenchRepublic, and resident of Paris, France, have invented certain new anduseful Improvements in Devices for Securing Tires to WVheel-Rims, ofwhich the following is a specification.

This invention relates to a device for securing tires to wheel rims andmore espe cially for securing in pneumatic tires the mantle of the tireto the wheel rim without it being necessary to use for this purpose thevalve of the air tube as this was the case until now.

The great advantage resulting from the use of this securing deviceresides in the fact, that the valve and that part of the air tube whichsurrounds it, are no longer submitted to the strains resulting from these curing of the mantle to the wheel rim and consequently will last muchlonger and will no longer be a cause of leakage.

Furthermore the securing device which forms the subject matter of thisinvention, will dispense with the employment of the so called safetybolts in use until now.

In the accompanying drawings: Figure 1 is a side elevation view of thesecuring device; F ig. 2 shows a longitudinal section of same while Fig.3 is a perspective view with parts shown in section of a part of a wheelrim on which the tire has been secured by means of the securing device.

This securing device which is preferably made of metal comprises a tube1 made integral at its upper end with a member 2 forming a head. Thishead, the lateral surfaces of which may be provided or not with ribs 3,has such a shape that it may easily engage the groove formed on theinside by the heels 4 of the mantle 5 of the pneumatic tire and thuspress these heels against the edges of the wheel rim 6.

The head 2 is provided with a central depression 7 at the place wherethe passage of the tube 1 opens out. The end of the tube 1 which ispositioned opposite the head 2, is provided with screw threads 8intended to receive a nut 9 and one or more washers 10.

The tube 1 is intended toreceive the valve 11 which is secured in theusual manner to the air tube 12 of the pneumatic tire and the securingnut 18 of which engages the depression 7 of the head 2. The length ofthe tube 1,is such that the end 14: of the valve the tube when the valveis in position in the latter.

\Vhen it is desired to fit the device to the wheel rim, one places thetube 1 on the valve attention being paid to the fact that the valve bein osition'in the said tube. \Vhen this operation is finished, the airtube slightly inflated and is thereafter placed in its mantle. The wholeis then put on the wheel and the tube 1 is placed into a hole providedto this end in the wheel rim. The washer or washers 10 are then slidover the projecting screw threaded end of the tube and finally the nut 9is screwed on the same end without being tightened. hen the wheel tireis entirely adjusted on the wheel and has been entirely inflated, thesecuring nut 9 is also tightened whereby the securing device is causedto descend and to cause the head 2 to exert a pressure on the innersurfaces of the mantle imprisoning the heels d of the latter without thevalve being needed as a stop or as a bearing point for securingpurposes. As the end of the valve freely projects from the tube 1 theinflation or deflation of the air tube can be carried out in the usualmanner.

Having now fully described my said invention what I claim and desire tosecure by Letters Patent is 1. In combination, a wheel rim formed withan opening and provided with inwardly extending flanges, a tire coverformed with ribs to [it against the inwardly extending flanges, a hollowsecuring device fitting in the opening in the rim and provided at oneend with an elongated head which engages the opposite inner walls of thetire cover, said elongated head having in its outer end a seat for avalve stem, means on the outer end of the hollow securing device toclamp the latter to the rim and draw the head against the tire cover toforce the ribs into engagement with the flanges.

2. A tire securing device comprising a tubular member, provided at oneend with an elongated head which is curved in cross section and formedin its upper surface with a seat, the opposite end of the tubular memberhaving threads, and a nut engaging the threads.

3. A tire securing device comprising a tubular member, provided at oneend with an elongated head which is curved in cross sec tion and formedin its upper surface with a seat, ribs 011 the curved surface of thehead, the opposite end of the tubular member having threads, and a nutengaging said threads. v

L. In combination, a wheel rim formed with an opening provided-withinwardly extending flanges, a tire cover open at its inner edge andformed opposite thereto with ribs, a securing device fitting in theopening in the rim and comprising an elongated head which is curved incross section, said elongated head having in its outer end a seat for avalve stem, a hollow stem projecting from the head and formed at its 0pposite end with screw threads, a nut engaging said threads to fasten thesecuring device in place, the tightening of the nut forc ing the wallsof the head against the free end of the cover to cause the ribs toengage under the inwardly extending flanges.

In testimony whereof I have hereunto set my hand in presence of twowitnesses.
